MKVToolnix v29.0.0 Final x86 / x64多語言中文正式版-MKV封裝工具

2018-12-02 Comments 0 Comment

MKV是一種優秀的多媒體容器格式，它可把多種不同編碼的視頻及16條或以上不同格式的音頻和語言不同的字幕封裝到一個MKV文件中，而MKVToolNix是一款免費開源的MKV編輯器和工具集，能夠合成，編輯Matroska MKV文件。

MKVToolNix包含了以下幾個MKV專用處理工具：
* mkvmerge：將多媒體文件封裝，合併，混流為MKV文件;
* mkvinfo：輸出MKV文件組件和編碼信息;
* mkvextract：從MKV文件中提取視頻，音頻和字幕軌道;
* mkvpropedit：直接修改現有MKV文件的屬性而無需重混流;
* mmg：mkvmerge GUI，並包含了章節編輯器和頭部編輯器。

MKVToolNix中的Mkvmerge GUI允許你導入多個視頻，音頻，字幕軌道，混流合併一個新的MKV文件，並可以設置導出視頻的寬高比，顯示比例，幀頻等等。

MKVToolNix中的MKVExtractGUI則可以從現有的MKV文件中提取其中的一個或多個視頻，音頻或者字幕信息，是專業的MKV分離工具。

MKV過程，提供了4種MKV切割模式，包括按尺寸，按時長，按特定時間碼和按分段。比之前介紹的所有支持MKV分割的工具都要好用，包括Boilsoft Video Splitter，SolveigMM AVI Trimmer等。

# Version 29.0.0 "Like It Or Not" 2018-12-01
## Important notes
* The string formatting library used was switched from `boost::format` to
  [`fmt`](http://fmtlib.net/). See the section "Build system changes" for
  details.

## New features and enhancements
* MKVToolNix GUI: added an option in the preferences for disabling automatic
  scaling for high DPI displays. Implements #2415.
* MKVToolNix GUI: the GUI will now prevent the system from going to sleep
  while the job queue is running. This feature is implemented for macOS,
  Windows and Linux/Unix systems where the `org.freedesktop.login1.Manager`
  D-Bus interface is available. Implements #2411.

## Bug fixes
* mkvmerge: chapter generation: the start timestamps of chapters generated in
  intervals was wrong for files whose smallest video timestamp was bigger than
  0. Fixes #2432.
* mkvmerge: MP4 reader: fixed handling of atoms whose size exceeds the parent
  atom's size. Fixes #2431.
* mkvmerge, MKVToolNix GUI's chapter editor: the chapter name template will
  now also be used when reading Ogg-style chapter files with empty chapter
  names. Fixes #2441.
* mkvextract: AAC: mkvextract will now write the program config element (PCE)
  before the first AAC raw data packet if the PCE is present in the
  `AudioSpecificConfig` structure in the `Codec Private` Matroska element. The
  PCE carries vital information about the number of channels and is required
  in certain cases. Fixes #2205 and #2433.
* mkvpropedit, MKVToolNix GUI's header editor: in situations when a one-byte
  space must be covered by a new EBML void element the following element must
  be moved up instead. If that moved element is a cluster, the corresponding
  cue entries will now be updated to reflect the cluster's new position. Fixes
  #2408.
* MKVToolNix GUI: Windows: the application manifest is now included properly
  so that Windows actually recognizes it. See #2415.

## Build system changes
* Qt's D-Bus implementation is now required for building on systems other than
  macOS and Windows,
* The `boost::format` library is not used anymore.
* The [`fmt` library](http://fmtlib.net/) is now required. Versions 3 and
  newer are supported. As not all Linux distributions include packages for the
  library, its release 5.2.1 comes bundled with MKVToolNix. The `configure`
  script will check for a system version of the library and use it if present
  and recent enough. Otherwise it will fall back to the bundled version and
  link that statically.

Version 28.2.0 "The Awakening" 2018-10-25
## Bug fixes
* mkvmerge, mkvinfo, mkvextract, mkvpropedit, MKVToolNix GUI's info tool & chapter editor: fixed a case of memory being accessed after it had been freed earlier. This can be triggered by specially crafted Matroska files and lead to arbitrary code execution. The vulnerability was reported as Cisco TALOS 2018-0694 on 2018-10-25.

28.1.0 "Morning Child" 2018-10-23

## Bug fixes
* mkvmerge: AV1 parser: fixed an error in the sequence header parser if neither the `reduced_still_picture_header` nor the `frame_id_numbers_present_flag` is set. Part of the fix for #2410.
* mkvmerge: AV1 parser: when creating the `av1C` structure for the Codec Private element the sequence header OBU wasn't copied completely: its common data (type field & OBU size among others) was missing. Part of the fix for #2410.
* mkvmerge: Matroska reader, AV1: mkvmerge will try to re-create the `av1C` data stored in Codec Private when reading AV1 from Matroska or WebM files created by mkvmerge v28.0.0. Part of the fix for #2410.
* MKVToolNix GUI: info tool: the tool will no longer stop scanning elements when an EBML Void element is found after the first Cluster element. Fixes #2413.

28.0.0 "Voice In My Head" 2018-10-20
## New features and enhancements
* mkvmerge: AV1 parser: updated the code for the finalized AV1 bitstream
  specification. Part of the implementation of #2261.
* mkvmerge: AV1 packetizer: updated the code for the finalized AV1-in-Matroska
  & WebM mapping specification. Part of the implementation of #2261.
* mkvmerge: AV1 support: the `--engage enable_av1` option has been removed
  again. Part of the implementation of #2261.
* mkvmerge: MP4 reader: added support for AV1. Part of the implementation of
  #2261.
* mkvmerge: DTS: implemented dialog normalization gain removal for extension
  substreams. Implements #2377.
* mkvmerge, mkvextract: simple text subtitles: added a workaround for simple
  text subtitle tracks that don't contain a duration. Implements #2397.
* mkvextract: added support for extracting AV1 to IVF. Part of the
  implementation of #2261.
* mkvextract: IVF extractor (AV1, VP8, VP9): precise values will be used for
  the frame rate numerator & denominator header fields for certain well-known
  values of the track's default duration.
* mkvmerge: VP9: mkvmerge will now create codec private data according to the
  VP9 codec mapping described in the WebM specifications. Implements #2379.
* MKVToolNix GUI: automatic scaling for high DPI displays is activated if the
  GUI is compiled with Qt ≥ 5.6.0. Fixes #1996 and #2383.
* MKVToolNix GUI: added a menu item ("Help" → "System information") for
  displaying information about the system MKVToolNix is running on in order to
  make debugging easier.
* MKVToolNix GUI: multiplexer, header editor: the user can enter a list of
  predefined track names in the preferences. She can later select from them in
  "track name" combo box. Implements #2230.

## Bug fixes
* mkvmerge: JSON identification: fixed a bug when removing invalid UTF-8 data
  from strings before they're output as JSON. Fixes #2398.
* mkvmerge: MP4/QuickTime reader: fixed handling of PCM audio with FourCC
  `in24`. Fixes #2391.
* mkvmerge: MPEG transport stream reader, teletext subtitles: the decision
  whether or not to keep frames around in order to potentially merge them with
  the following frame is made sooner. That avoids problems if there are large
  gaps between teletext subtitle frames which could lead to frames being
  interleaved too late. Fixes #2393.
* mkvextract: IVF extractor (AV1, VP8, VP8): the frame rate header fields
  weren't clamped to 16 bits properly causing wrong frame rates to be written
  in certain situations.
* mkvpropedit, MKVToolNix GUI's header editor: fixed file corruption when a
  one-byte space must be covered with a new EBML void element but all
  surrounding elements have a "size length" field that's eight bytes long
  already. Fixes #2406.
